Specification of Letters Patent.

Patented Aug. 11, 1914..

Application filed November 19, 1913. Serial No. 801,868.

To all whom t may concern.'

Be it known that I, JACOB HENRY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Window-Shade Adjusters, of which the following is a specification.

This invention relates to window shade adjusters, and its object is to provide means that may be attached to a window casing to support the common roller shade in such a manner that the shade and roller may be lowered and raised, and iixed at any desired height upon the window, and to maintain the roller in a horizontal position without interfering with the normal action of the roller in letting down or rolling up the shade to cover more or less of the window.

To this end, my invention consists in the construction and combination of parts forming a window shade adjuster hereinafter more fully described and particularly stated in the claim, reference being had to the accompanying drawings, in which:

Figure I is a face view of a window casing and shade, showing my adjuster in serv ice. Fig. II is a top view, partly in horizontal section, of a carrying device at one d of the shade roller. Fig. III is a side view of one of the carriers.

Numeral 5 represents a window casing; numeral 6, a shade mounted on a roller 7 having the usual internal winding springnot shownand projecting bearing pins 8. These pins are mounted in carriers 9 and 10 of peculiar form. Rods 11, fixed to the window casing by means of posts 12, serve as guide rails for the carriers 9. Cords 13, attached to the two carriers, pass over pulleys 14, 15 that are attached to the casing 5, and both cords passing down from the pulley 15 are permanently secured to a ring 16 when taut and the roller is held horizontally. A. cord 17 is attached to the ring by which to operate it, and hitch nails 18, of brass or other ornamental character, may be driven into the casing, in which the ring may be hitched to hold the shade at desired points of elevation.

The carriers 9, 10 are formed of sheet metal bent around the rail 11 to slide thereon, and extending at one side beyond the rail with a return bend, as shown at 19, and perforated, as at 20, to receive the roller pins 8, and at 21 to receive the cords 13. The carrier 9 shown in Figs. II and III has the perforation 20 slotted to the upper edge to admit the flattened pin of the roller, and the opposite carrier 10 will have the bearing hole for a round pin, both as usual. The post 12 is a piece of flat metal like hoop iron or brass, bent tightly around the rail 11, then closed together along its body 22, and spread out to form feet 28 which are perforated for nails or screws to be secured to the window casing. These may be secured to the sides 24 of the casing if the shade is to be hung within the casing. This whole device is extremely simple and inexpensive; both the carriers and posts being only short lengths of hoop metal perfo-rated and bent, the rods, rings and pulleys being carried in stock by hardware dealers. By means of this adjuster' the shade may be located to permit the free passage of air either above or below it, according as it may be desired to open the window at the top or bottom. By having a series of hitch nails one may be selected to hold the shade where it will admit the greatest amount of air and yet exclude direct rays of the sun, or impertinent observation from some neighboring window, and the shade may be secured at this same height any number of times without further adjustment. Screws, knobs or other devices that will readily engage the ring may serve in place of nails as hitches.

I claim:

In a window shade adjuster, a pair of side rails and means for holding them parallel to the window casing and at a little distance therefrom; a carrier of sheet material bent around each rail to slide thereon and extending beyond the side thereof with a return bend perforated to receive a bearing pin of the window shade in line between the rails whereby the carrier is prevented from turning away from a bearing pin and dropping it.

In testimony whereof I affix my signature in presence of two witnesses.
